I just found out the Citric acid is a good organic way to down your PH , Has anyone used this method? If so please please take me through how much you used, what kind, Etc...

Ok so i got it figured out.. about 1/4 lemon juice brings a gallon of tap water from 7.4 to 6.3. Perfect..

I think pH up and down are organic by default because it is natural, but I could be wrong. Also, 6.3 is pretty high for your pH. Optimal pH is around 5.7 or so. I like to keep mine right around 5.8. Using lemon juice is going to get expensive fast.

i guess if one was growing in the ground you could lay out lemon around the garden and water with a sprinkler, thoughts on that
